General
Description
The TYCO DV-5A Automatic Water
Control Valves are diaphragm type
valves that can be used in remote-
resetting deluge fire protection
systems. When properly trimmed,
the DV-5A Valve with Remote-Reset-
ting, Pressure-Reducing Trim can be
opened and closed during a full-flow
condition from a remote location. Key
features are as follows:
• Pressure-Reducing function main-
tains pre-set outlet pressure.
• Remote-resetting feature provides
the ability to reset the valve from one
or more locations.
• Compact, space-saving design
reduces valve room footprint and
construction costs.
• Electric actuation is compatible with
many types of automatic and manual
release options.
• Actuation of fire alarms upon system
operation is provided.
The DV-5a Valves are offered with the
DV-5a Valve and separately ordered
semi-assembled trim shown in Figure
6, or, for ease of installation, with the
DV-5a Valve completely trimmed with or
without a System Main Control Valve.
The diaphragm style design of the
DV-5A Valve allows external resetting,
providing for easy resetting of a deluge
system without having to open a valve
handhole cover to manually reposition
a clapper and/or latch mechanism.
Simply re-pressurizing the diaphragm
chamber resets the valve.
Operation of the DV-5A Valve with
Remote-Resetting, Pressure-Reducing
Trim is provided by an automatic elec-
tric detection system or remote manual
electric activation. The easily installed
trim configuration for the DV-5A Valve
with Remote-Resetting, Pressure-
Reducing Trim provides for emergency
(manual) release of the valve at the
valve location.
The DV-5A features internal and exter-
nal coating of the valve to provide
corrosion resistance. The external cor-
rosion resistance of the epoxy coating
permits the use of the DV-5A in cor-
rosive atmospheres associated with
many types of industrial processing
plants and outdoor installations.
NOTICE
The DV-5A Valves described herein
must be installed and maintained in
compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION (NFPA), in addition to
the standards of any other authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.

Design
Criteria
The following items must be consid-
ered and applied accordingly for TYCO
DV-5A Valve with Remote-Resetting,
Pressure-Reducing Trim installations.
NOTICE
The owner is responsible to design into
the system a releasing circuit such that
a Solenoid Valve is properly configured
to enable remote resetting.
The building owner must be informed
of the capabilities and limitations of a
remote-resetting, pressure-reducing
system as it pertains to the possibil-
ity of an inadvertent remote closing
of the DV-5A Valve during a fire condi-
tion. Therefore, personnel responsible
for the fire protection system must be
fully trained on system components
and required actions in the case of an
alarm.
The Control Panel, Detectors, and Pull
Stations are to be installed in accor-
dance with their laboratory listings and
approval.
System piping is to be installed so that
it is self-draining. TYCO Model AD-2
Automatic Drain Valves can be used
to drain low sections of pipe as nec-
essary. For more information, refer to
Technical Data Sheet TFP1632.

Operation
The TYCO DV-5a Valve is a diaphragm
style valve that depends upon water
pressure in the Diaphragm Chamber
(Ref. Figure 2A) to hold the Diaphragm
closed against the water supply
pressure.
When the DV-5A Valve with Remote-
Resetting, Pressure-Reducing Trim
is set for service, the Diaphragm
Chamber is pressurized through the
trim connections from the inlet side of
the system’s main control valve.
With reference to Figure 4, initial acti-
vation of the Solenoid Valve due to
electrical detection or activation of the
electrical manual pull station results in
the latched opening of the Solenoid
Valve. Opening of the Solenoid Valve
in the Remote-Resetting, Pressure-
Reducing Trim releases water from the
Diaphragm Chamber faster than it can
be replenished through the Restriction
in the Diaphragm Chamber Supply
Connection provided in the trim. This
release results in a rapid pressure
drop in the Diaphragm Chamber, and
the force differential applied through
the Diaphragm that holds it in the set
position is reduced below the valve trip
point.
The water supply pressure then forces
the Diaphragm open, permitting water
to flow into the system piping, as well
as through the Alarm Port to actuate
system alarms.
To remotely reset the DV-5a Valve, the
voltage to the Solenoid Valve must be
transferred to the appropriate terminals
of the Solenoid Valve (Ref. Figure 5)
resulting in the latched closure of the
Solenoid Valve. Closing of the Sole-
noid Valve in the Remote-Resetting,
Pressure-Reducing Trim permits the
Diaphragm Chamber to repressurize.
This repressurizing results in a pressure
increase in the Diaphragm Chamber.
The resulting force repressurizes the
Diaphragm Chamber, closing the valve
and stopping the flow of water into the
system piping.

Heat tracing of the DV-5a Valve or its
associated trim is not permitted. Heat
tracing can result in the formation of
hardened mineral deposits that are
capable of preventing proper operation.
Always open the system control valves
slowly to avoid a sudden rush of water
entering the system.
The DV-5a Valve is to be installed in
accordance with the following criteria:
Step 1. All nipples, fittings, and devices
must be clean and free of scale and
burrs before installation. Use pipe
thread sealant sparingly on male pipe
threads only.
Step 2. The DV-5a Valve must be
trimmed in accordance with Figure 6.
Note: If the addition of an Alarm Control
Valve is desired or required by the local
AHJ, the Alarm Control Valve noted as
Item H in Figure 9 is to be a separately
ordered electronically supervised nor-
mally open valve.
Step 3. Care must be taken to ensure
that check valves, strainers, globe
valves, etc. are installed with the flow
arrows in the proper direction.
Step 4. Drain tubing to the Drip Funnel
must be installed with smooth bends
that will not restrict flow.
Step 5. The Main Drain and Drip Funnel
Drain may be interconnected pro-
vided a check valve is located at least
12 in. (300 mm) below the Drip Funnel.
Installation
The TYCO DV-5a Valve is to be installed
in accordance with this section.
NOTICE
DV-5A Automatic Water Control Valves
are designed to be used in freshwa-
ter systems. When the supply is from
an alternative source such as brackish
water, saltwater, or contains additives
such as foam, the limited warranty is
reduced to one year from the time of
installation. An increase in frequency of
inspections is required when the valve
is exposed to such supplies and other
corrosive conditions or chemicals that
could impact valve materials or the
operation of the assembly. The system
and all components must be designed
accordingly for the increased demand.
It is required to thoroughly flush the
valve and trim assembly with freshwa-
ter and reset to the set condition after
each operation.
Proper operation of the DV-5a Valves
depends upon their trim being installed
in accordance with the instructions
given in this technical data sheet.
Failure to follow the appropriate trim
diagram may prevent the DV-5a Valve
from functioning properly, as well as
void approvals and the manufacturer’s
warranties.
The DV-5a Valve must be installed in a
readily visible and accessible location.
The DV-5a Valve and associated trim
must be maintained at a minimum tem-
perature of 40°F (4°C).
Step 6. Suitable provision must be
made for disposal of drain water. Drain-
age water must be directed such that
it will not cause accidental damage to
property or danger to persons.
Step 7. Connect the Diaphragm Supply
Valve to the inlet side of the System
Main Control Valve in order to facili-
tate setting of the DV-5a Valve. Refer
to Figure 9.
NOTICE
The connection to the Diaphragm
Supply Valve should be as short as
practical and from the same water
supply as the system.
Step 8. Unused Pressure Alarm Switch
connection must be plugged.
Step 9. Conduit and electrical connec-
tions are to be made in accordance
with the applicable standards of the
approval agency.
Step 10. Before a system hydrostatic
test is performed, the DV-5a Diaphragm
Chamber is to be depressurized, the
Automatic Drain Valve is to be tem-
porarily replaced with a plug, and the
Diaphragm Cover Bolts must be uni-
formly and securely tightened using a
cross-draw sequence. After tighten-
ing, double-check to make certain that
all of the Diaphragm Cover Bolts are
securely tightened. Refer to Table C in
the Care and Maintenance section for
torque specifications.

Valve Setting
Procedure
Perform Steps 1 through 13 when ini-
tially setting the TYCO DV-5A Valve with
Remote-Resetting, Pressure-Reducing
Trim for service or after an operational
test of the fire protection system (Ref.
Figure 9).
Step 1. Close the System Main Control
Valve (B).
Step 2. Close the Diaphragm Supply
Valve (P).
Step 3. Open the Main Drain Valve
(D) and System Drain Valve (E). Close
the System Drain Valve (E) after water
ceases to discharge. Leave the Main
Drain Valve (D) open.
At this time make certain that the
Pressure Gauge Valves and the Alarm
Control Valve (H), as applicable, are
open.
Step 4. Depress the plunger of the
Automatic Drain Valve (F) to verify that
it is open.
Step 5. Clean the Diaphragm Supply
Strainer (Q) by removing the clean-
out plug and strainer basket. The Dia-
phragm Supply Strainer (Q) may be
flushed out by momentarily opening
the Diaphragm Supply Valve (P).
Step 6. Reset the electric detection
system in accordance with the manu-
facturer’s instructions to de-energize
the solenoid valve.
Step 7. Operate (open) the Manual
Control Station (M) and then open
the Diaphragm Supply Valve (P). After
unaerated water ceases to discharge
from the Manual Control Station (M)
drain tube, slowly close the operating
lever by pushing it up. Do not close the
hinged cover at this time.
Step 8. Inspect drain connections from
the Manual Control Station and Sole-
noid Valve. Before proceeding to the
next step, correct any leaks.
Step 9. Verify the ability for the DV-5A
Diaphragm to hold pressure as follows:
• With the diaphragm chamber pres-
surized per Step 7, temporarily close
the Diaphragm Supply Valve (P), and
then observe the Diaphragm Gauge
(K) for a drop in pressure.
• If a drop in pressure is noted, the
DV-5A Diaphragm is to be replaced
and/or any leaks must be corrected
before proceeding to the next step.
• If the Diaphragm Gauge (K) indicates
no drop in pressure, re-open the Dia-
phragm Supply Valve (P) and pro-
ceed to the next step.
Step 10. Partially open the System
Main Control Valve (B). Slowly close
the Main Drain Valve (D) as soon as
water discharges from the Main Drain
Valve (D). Observe the Automatic Drain
Valve (F) for leaks. If there are leaks,
determine/correct the cause of the
leakage problem before proceeding.
NOTICE
When the System Main Control
Valve (B) is partially opened, the pres-
sure on the DV-5A Diaphragm Chamber
may increase. This increase in pressure
is normal, and if the pressure is greater
than the valve trim maximum pressure
rating provided in the Technical Data
section, the pressure is to be relieved
to at least the valve trim pressure rating
by partially and temporarily opening the
Manual Control Station (M); however,
do not allow the pressure as indicated
on the Diaphragm Gauge (K) to drop
below the supply pressure shown on
the Water Supply Gauge (J), since
this action may result in tripping of the
DV-5A Valve.
Step 11. Close the hinged cover of the
Manual Control Station Valve (M) and
insert a new break rod in the small hole
through the top of the enclosing box.
Step 12. Fully open the System Main
Control Valve (B).
Step 13. After setting a fire protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.
Adjusting Pilot
Valve Pressure
A minimum flow of 100 gpm (380 lpm)
is required to adjust the Pilot Valve’s
pressure.
NOTICE
After any downstream pressure adjust-
ment, the following items are to be
recorded on a tag attached to the valve:
• Valve installation location
• Inlet static pressure
• Inlet residual pressure
• Outlet residual pressure
• Intended outlet flow
The tag is not to be removed until after
the system has been accepted by the
authority having jurisdiction. It is rec-
ommended that the tag not be removed
even after acceptance by the author-
ity having jurisdiction unless another
means of record keeping is maintained.
Pressure in the Pilot Valve is factory-
set. To re-adjust the pressure, set
the valve first, according to the Valve
Setting Procedure described in this
technical data sheet, then follow the
steps below. Refer to Figure 10 as
needed.
Step 1. To set the pressure in the field,
trip the valve manually or electrically.
It is recommended that the valve is
tripped electrically to test the entire
system.
Step 2. Remove the Tamper Cap of
the Pilot Valve by first loosening the
Set Screw and unscrewing the Tamper
Cap.
Step 3. If surging flow occurs, attempt
to bleed trapped air from the system via
the Automatic Drain Valve.
Step 4. Loosen the Lock Nut on the
Adjusting Screw of the Pilot Valve.
Step 5. Turn the Adjusting Screw
clockwise to increase outlet pressure
or counterclockwise to decrease outlet
pressure.
Step 6. Observe the Outlet Pressure
Gauge for changes. The valve needs
time to reach the new set point after
changing the preset pressure. Turn the
Adjusting Screw ½ turn at a time until
the pressure stabilizes.
If necessary, turn the Adjusting Screw
again until the desired set point is
achieved.
Step 7. After the desired performance,
tighten the Lock Nut.
Step 8. Replace the Tamper Cap and
tighten the Set Screw.
Step 9. Ensure that the system is prop-
erly drained.
The DV-5A Deluge Valve is now set for
service.

Care and
Maintenance
The following procedures and inspec-
tions must be performed as indicated,
in addition to any specific require-
ments of the NFPA and any applicable
standards recognized by the Approval
agency. Any impairment must be imme-
diately corrected (Ref. Figure 9).
NOTICE
If the water supply needs to be shut off
to the DV-5a valve and trim and cannot
be shut off upstream of the system,
close the System Main Control Valve
(B), the Diaphragm Supply Valve (P),
and the Water Supply Shut-Off Valve
(R). This will allow any trim above the
System Main Control Valve (B) to be
taken apart for service if necessary.
The frequency at which the following
procedures and inspections are to be
performed are to be in accordance with
the NFPA and any applicable specific
requirements of the standards recog-
nized by the Approval agency.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down
the affected fire protection systems
must first be obtained from the proper
authorities and all personnel who may
be affected by this action must be
notified.
The owner is responsible for the
inspection, testing, and maintenance
of their fire protection system and
devices in compliance with this docu-
ment, as well as with the NFPA and any
applicable standards recognized by the
Approval agency. Contact the install-
ing contractor or product manufacturer
with any questions.
Some procedures in this section result
in the operation of the associated
alarms. Notify the owner and the fire
department, central station, or other
signal station to which the alarms are
connected before performing the tests.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with the
NFPA and any applicable standards
recognized by the Approval agency.
Drop in Water Supply Pressure
Below Normal Range
NOTICE
If the water supply pressure is signif-
icantly reduced below the normally
expected static pressure range (as
could occur in the case of a water main
break or repair), and there is a subse-
quent drop in the diaphragm chamber
water pressure below its normal range
(for example, due to a leak in a piping
connection to or from the diaphragm
chamber or, a leak in the diaphragm
chamber check valve caused by dirt or
debris in the check valve seal area), a
deluge valve such as the DV-5A could
inadvertently trip, if its water supply
pressure is quickly restored.
A drop in the water supply pressure
to below its normal range (as in the
case of an interrupted water supply
condition) constitutes an emergency
impairment.
Should this condition occur, immedi-
ately close the main control valve and
use the following procedure to reset the
system:
Step 1. Prior to the water supply pres-
sure being restored to the closed main
control valve, note the pressure indi-
cated by the diaphragm chamber
pressure gauge and determine if
the pressure is within the normally
expected range.
Step 2. If the diaphragm chamber pres-
sure is below the normal range, check
for and correct any source of leakage
from the diaphragm chamber prior to
resetting the system.
Step 3. After the water supply pres-
sure is restored to the main control
valve, reset the DV-5A Valve in accor-
dance with the Valve Setting Procedure
section.
NOTICE
For fire protection systems subject to
an emergency impairment caused by
an interrupted water supply condition,
it is recommended that consideration
be given to installing a low water supply
pressure switch with the appropriate
alarm/indications to monitor the water
supply pressure.
Waterflow Alarm Test Procedure
To test the waterflow alarm, open the
Alarm Test Valve (G), which will allow a
flow of water to the Waterflow Pressure
Switch (C) and/or Water Motor Alarm.
Upon satisfactory completion of the
test, close the Alarm Test Valve (G).
To ensure drainage of the alarm line,
depress the plunger on the Automatic
Drain Valve (F).
Electric Actuation
Operation Test Procedure
Proper operation of the DV-5A Valve
(i.e., opening of the DV-5A Valve as
during a fire condition) must be veri-
fied as follows:
Step 1. If water must be prevented
from flowing beyond the riser, perform
the following steps.
• Close System Main Control Valve (B).
Open Main Drain Valve (D).
• Open System Main Control Valve (B)
one turn beyond position at which
water just begins to flow from Main
Drain Valve (D).
• Slowly close the Main Drain Valve (D).
Step 2. Test the deluge releasing panel
in accordance with the manufacturer’s
instructions to energize the solenoid
valve.
Note: Be prepared to quickly perform
Steps 3, 4, and 5 if water must be pre-
vented from flowing beyond the riser.
Step 3. Verify that the DV-5A Valve has
tripped, as indicated by the flow of
water into the system.
Step 4. Close the System Main Control
Valve (B).
Step 5. Close the Diaphragm Supply
Valve (P).
Step 6. Reset the DV-5A Valve in accor-
dance with the Valve Setting Procedure.
Electric Actuation
Solenoid Valve (N) Test Procedure
Proper operation of the Solenoid Valve
(N) for electric actuation must be veri-
fied at as follows:
Step 1. Close the System Main Control
Valve (B).
Step 2. Open the Main Drain Valve (D).
Step 3. Test the deluge releasing panel
in accordance with the manufacturer’s
instructions to energize the Solenoid
Valve (N).
Step 4. Verify that there is a flow of
water from the Solenoid Valve (N) drain
connection.
Step 5. Verify that the Diaphragm
Chamber pressure has decreased
to below 25% of the water supply
pressure.
TFP1326
Page 17 of 22
Step 6. Reset the electric detection
system in accordance with the manu-
facturer’s instructions to de-energize
the Solenoid Valve (N), and proceed
as follows:
• Water should cease draining from the
Solenoid Valve (N).
• Pressure will then build up in the
DV-5A Diaphragm Chamber.
• After system pressure is restored
in the DV-5A Diaphragm Chamber,
inspect the Solenoid Valve (N) for
leaks at the drain tube. Any leaks
must be corrected before proceed-
ing to the next step. The Solenoid
Valve (N) discharges water into the
riser and must be drained at the con-
cluson of this test.
Step 7. Partially open the System
Main Control Valve (B). Slowly close
the Main Drain Valve (D) as soon as
water discharges from the Main Drain
Valve (D). Observe the Automatic Drain
Valve (F) for leaks. If there are leaks,
determine/correct the cause of the
leakage problem. If there are no leaks,
the DV-5A Valve is ready to be placed
in service and the System Main Control
Valve (B) must then be fully opened.
Internal Valve Inspection
Once every five years during the annual
operational test procedure and prior
to the DV-5a Valve being reset and
with the DV-5a Valve de-pressurized,
the interior of the DV-5a Valve must
be cleaned and inspected for wear
and damage. Damaged or worn parts
must be replaced. (Replacement of the
Diaphragm every ten years is recom-
mended, or more frequently if inspec-
tions and/or wear and tear warrant
more frequent replacement.)
NOTICE
The Diaphragm Cover may be removed
between Steps 4 and 5 of the reset-
ting instructions, since at that point the
DV-5a Valve should be de-pressurized
as evident by a zero gauge reading on
the Diaphragm Gauge (K) and Water
Supply Gauge (J), as well as no water
discharging from the Automatic Drain
Valve (F).
Ensure that the Diaphragm Supply
Valve (P) and the System Main Control
Valve (B) are closed before removing
the cover.
To perform internal valve inspection
between Steps 4 and 5 of the Valve
Setting Procedure, remove the dia-
phragm cover as follows:
Step 1. Close the Inverted Flare Shut-
Off Valve (R).
Step 2. Remove the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 3. Loosen the union securing the
Solenoid Valve (N).
Step 4. Loosen and remove the union
between the Diaphragm Cover and the
trim and remove the trim.
Step 5. Remove the Diaphragm Valve
Cover hardware, then slowly remove
the Diaphragm Cover and perform
internal valve inspection. Clean the
valve interior and replace parts as
necessary.
After cleaning and inspecting valve
interior, and replacing parts as nec-
essary, reinstall the Diaphragm Cover
by completing the following steps to
assure the Diaphragm Cover Fasteners
are uniformly and securely tightened.
Step 1. With reference to Figure 1,
ensure that the Diaphragm is properly
oriented and that the proper hardware
arrangement is utilized when assem-
bling the Diaphragm Covers. The hard-
ware arrangements differ depending on
the size of the DV-5a Valve.
Step 2. By first using the Long Hex
Bolts, support of the Diaphragm Cover
will be provided before installing the
Short Hex Bolts. Align Diaphragm in
proper orientation with Valve Body, and
then align Diaphragm Cover in proper
orientation with Valve Body. Hand-
tighten all fasteners.
Step 3. Using crossdraw sequence
to assure uniformity, wrench-tighten
Long Hex Bolts and Short Hex Bolts
to appropriate torque values. Repeat
crossdraw sequence two to three
times at incremental torque valves
until reaching the torque valves found
in Table C.
Step 4. Inspect to assure all Hex Bolts
are securely tightened.
Step 5. Using the union, the trim to the
Diaphragm Cover.
Step 6. Using the union, secure the
solenoid Valve (N).
Step 7. Replace the Copper Tube
Fitting between the Diaphragm Supply
Valve (P) and the Inverted Flare Shut-
Off Valve (R).
Step 8. Ensure that the unions and flare
fittings are securely tightened.
Step 9. With the Diaphragm Supply
Valve (P) closed, fully open the Inverted
Flare Shut-Off Valve (R) stainless steel
screw (approximately ½ in.) until resis-
tance is met so as not to break the
internal roll-pin. The internal roll-pin
stops the removal of the Inverted Flare
Shut-Off Valve (R) stainless steel screw.
Step 10. Proceed to step 5 of the Valve
Setting Procedures section in this data
sheet.
NOTICE
If the water supply contains chemicals
which tend to attack a polyester fabric-
reinforced, EPDM rubber or the five
year inspection indicates a build-up of
debris within the DV-5A Valve that could
affect its proper operation, then the
frequency of the internal valve inspec-
tion procedure must be appropriately
increased.
With reference to Figure 1, make
certain that the Diaphragm is correctly
oriented; otherwise, the DV-5A Valve
cannot be properly set.
Under-tightening the Diaphragm Cover
Bolts can result in internal and external
leakage.
Use only TYCO replacement fasteners
as specified in Figure 1.
Do not apply adhesives, lubricants, or
other substances to the Diaphragm or
Valve Body.
